I just got done doing test runs on the new map the night before. I was up till 3am, and then left for Sacramento at 5am! I was disappointed with my Vbox results and almost didn't want to make the trip. Furthermore when I got there, it was pretty damn hot to be changing tires, etc. The sun was really strong to the point where I was getting a sunburn. I was cursing the weather and thought to myself, "why me?". So considering the factors, I was pretty pleased with my results.

I think I could have launched harder, but I didn't want to risk spinning and ruining the run. Its kind of hard when you have to wait in line as the dragsters, motorcycles, etc, go. In the meanwhile, your engine is getting hot, and the ambient temps are going up. So you just can't afford to experiement too much. I have already confirmed in my testing how much ambient temps can help. So if it were 56F instead of 65F, I think I would have been pushing over 121mph traps.

Again, the car ran great, no stumbling or hiccups.
FYI, this morning on 91 octane, and the newer map#6 equivalent, the car was runnning 115.6 mph on the Vbox.

It is interesting how your performance can vary by the type of gas you are using, and ambient conditions, etc.
